Patent CA-2206732-A1 (CA)
Inventor: BIELFELDT FRIEDRICH B
IPC: B30B5/06
Filed: 1997-05-29
Abstract: The invention relates to a method of controlling the press force on the press heating plates within the press length of an operating cycle in the production of particleboards, fiberboards and similar wooden-material boards, and also of plastic sheets, using a continuously operating press.  In order to increase the longitudinal deformation gradient of the press heating plates, the invention consists in the fact that, in the event of a reduction of the specific press force from the maximum toward zero, the setting force for the longitudinal deformation of the press heating plates is increased accordingly, or, in the event of an increase in the specific press force from zero toward the maximum, the setting force for the longitudinal deformation of the press heating plates is reduced accordingly.

Title: Coating of a hydrophobic polymer substrate with a nonstoichiometric polyelectrolyte complex
Inventor: GILLBERG-LAFORCE GUNILLA ELSA
IPC: C08J7/04
Filed: 1997-06-16
Abstract: A method of coating the surface of a substrate, such as a film or a fibrous web, which is composed of a hydrophobic polymer. The method involves providing a solution of a first polyelectrolyte having ionizable groups and a solution of a second polyelectrolyte having ionizable groups. The two solutions then are mixed under conditions adapted to result in the formation of a nonstoichiometric polyelectrolyte complex. Finally, the surface of the hydrophobic polymer substrate is contacted with a solution of the complex under conditions sufficient to result in the coating of the surface of the substrate with the complex. The ionizable groups of the second polyelectrolyte have a latent charge opposite the latent charge of the ionizable groups of the first polyelectrolyte. Moreover, the amounts of the first and second polyelectrolytes are selected to give a ratio of the number of ionizable groups in the first polyelectrolyte to the number of ionizable groups in the second polyelectrolyte of at least about 2, and the molecular weight of the first polyelectrolyte is at least about 40,000 daltons and at least about 2 times the molecular weight of the second polyelectrolyte.

Title: Medicinal fluid pump having multiple stored protocols
Inventor: MARTTILA CONSTANCE M
IPC: A61M5/172
Filed: 1996-01-05
Abstract: A pump (23) used to infuse a fluid into a patient (27) is controlled in accordance with a plurality of parameters entered by an operator. These parameters define a protocol that is applied in controlling the operation of the pump to determine the rate, volume, and timing of the fluid infusion. The operator enters the parameters using a keypad (16) in response to prompts provided on a display (18). Once the parameters for a current protocol are entered, they can be stored as a speed protocol by selecting that option from a menu appearing on the display. Up to three speed protocols can be stored in memory in the disclosed preferred embodiment. When preparing to infuse a medicinal fluid, an operator can elect to enter a new protocol or to select an appropriate speed protocol stored in memory for loading as the current protocol. Use of stored speed protocols saves time and reduces the likelihood of errors that can occur when data defining the parameters controlling the infusion process are entered by an operator.

Patent CA-2213984-A1 (CA)
Inventor: MEIER ROBERT C
IPC: H04W36/00
Filed: 1997-08-22
Abstract: A premises based wireless network having a multi-segment wired network and a plurality of wireless access points connected to the wired network. The wired network operates according to a wired network protocol which may be the Internet Protocol. Wireless terminals communicate with the wireless access points according to a wireless network protocol, inconsistent with the wired network protocol. Each of the wireless terminals has a wired network address corresponding to one of the wireless access points. As the wireless terminals roam throughout the premises, protocol tunnels route communications between wireless terminals, thereby preserving communications while roaming by allowing the wireless terminals to retain their wired network addresses during the ongoing communications. An address resolution packet proxy server presents flooding of the wireless network with address resolution packets. The address resolution packet proxy server may act as a full proxy for wireless terminals connected to a respective wireless access point thereby relieving the wireless terminal from responding to address resolution packet requests. An augmenting agent provides enhanced services within a wireless network device by enhancing operation of drivers and protocol operators. The augmenting agent may be either a shim or monitoring agent that monitors, communications between the protocol operator and the drivers. When required, the augmenting agent participates to alter operations to provide enhanced services. The enhanced services include encypherment/encryption, device authentication, global network configuration, diagnostics such as loop-back testing, signal strength feedback, wireless retry counts, network route tracing, network management, solving out-of-sequence packet race conditions and filtering and flooding restriction operation.

Patent CA-2218875-A1 (CA)
Inventor: BLOCH WILL
IPC: C12Q1/68
Filed: 1992-07-20
Abstract: Improvements to the in situ polymerase chain reaction (PCR), a process of in vitro enzymatic amplification of specific nucleic acid sequences within the cells where they originate, can be achieved by changing the way that the enzymatic reaction is started. Reaction initiation is delayed until the start ofPCR thermal cycling, either by withholding a subset of PCR reagents from the cellular preparation until the preparation has been heated to 50° to 80° C, immediately before thermal cycling is begun, or by adding to the PCR reagents a single-stranded DNA binding protein which blocks reaction at temperatures below about 50°C. If the in situ PCR is performed on cellular preparations already attached to a microscope slide, thermal cycling also is facilitated by use of a thermal cycler sample block or compartment designed optimally to hold the microscope slide and any vapor barrier covering the slide.
